Perhaps a German failure at Eben Emael makes no difference but there is a counter argument. Eben Emael's guns commanded three bridges over the Meuse and Albert Canal. These bridges were also attacked by German paratroops. If two of the bridges had not been taken intact or if the guns of Eben Emael had prevented the German's from using the bridges for perhaps two days (the Belgians hoped to hold the Albert Canal for 5 days), Hoepner's 16th Panzer Corps (3rd and 4th Panzer Divisions) could not have advanced across the bridges towards the Gembloux Gap. OTL they were met and stopped by Prioux's Cavalry Corps of the French 1st Army (2nd DLM and 3rd DLM) in the Battle of Hannut on 12th -13th May. This was the largest tank battle of the Battle of France involving about 1,500 tanks. If it had not occurred, the French would have had two uncommitted armoured divisions under a fairly competent commander north of the main German attack across the Meuse on 13th May.
It is likely that Prioux's force would have been sent south to help Corap's 9th Army. We can argue that the French would not have reacted quickly enough but it is just possible that 9th Army would have held significantly longer and that the two Divisions Cuirassée de Réserve, 2nd and 3rd DCR, would not have disintegrated without much fighting. Guderian's Corps would still have broken through further south but might not have been allowed to advance alone. Just possibly the Anglo-French armies would have avoided being cut-off in Belgium, in which case even if France were later defeated it would be only after a significantly longer campaign.
